Native scaling
Drawing Linux windows closer to the Mac's own interface size.
Off by default. Linux windows are normally drawn one X pixel per point, which is what every app has been tested at. With this on they are drawn closer to the Mac's own interface size.
Worth trying if Linux apps look small next to Mac ones. Some apps lay out well when scaled and some do not — toolkits vary in how much they believe the display's reported size — which is why it is off by default rather than on.
Applies to apps launched after the change.
